Abstract

Przedmiotem wynalazku jest soczewka wieloogniskowa (1), zwłaszcza soczewka wewnątrzgałkowa lub soczewka kontaktowa, z ogniskiem refrakcyjnym (Fr) i pierwszą i drugą strukturą dyfrakcyjną, które co najmniej częściowo nakładają się na siebie wzajemnie, przy czym obie struktury dyfrakcyjne są różne, i przy czym ognisko pierwszego rzędu i pierwszej struktury dyfrakcyjnej (6) pokrywa się z ogniskiem pierwszego rzędu drugiej struktury dyfrakcyjnej. Wynalazek dotyczy ponadto sposobu wytwarzania takiej soczewki wieloogniskowej (1).The present invention relates to a multifocal lens (1), especially an intraocular lens or contact lens, with a refractive focal point (Fr) and first and second diffraction structures that at least partially overlap each other, both diffractive structures being different, and the first-order focus and first diffractive structure (6) coincides with the first-order focus of the second diffractive structure. The invention further relates to a method for producing such a multifocal lens (1).
